i've only sharpen to level 9 (act III), but as i put virtually ALL my attribute points into agility and strength, attaining the 56 required agility for my one hander was relatively easy.
however, if sharpen proceeds upward of say level 13-14 and the agility requirement becomes 80-something, it will indeed start to require gold charming my itmes.
of course, the bow still kicks any swords butt! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
